So I'm relatively new to Rogue Trader, and I'm trying to work out the background for a campaign. I have a few questions I've been unable to answer and I was hoping that you fine folk could help.
Do the Great Navigator Houses have ships/fleets of their own? I know that page 11 of the Navis Primer says "they do not generally maintain the sort of visible power structures most other Imperial institutions rely upon [such as] fleets of starships bearing their livery", but I've seen allusions to cases where these enormously wealthy houses have done something of the sort.
In particular, I recall reading somewhere on these forums that the largest civilian fleet in the Imperium was owned by one of the Navis Nobilite Great Houses, and its number was 47 hulls. This information was linked to the Navis Primer , but no page number was given. Having just finished reading through the Navis Primer again for the third time looking for this information, I find myself at a loss.
It does not seem at all strange to me that a Navigator House might have at least two or three vessels of its own to facilitate the movement of its scions from one important task to another. Even just holding shares in different ventures across interstellar distances would require extensive travelling to attend shareholder meetings and the like. The ships wouldn't even need to be all that large or heavily armed. Travelling in a convoy with other vessels would provide significant protection against pirates, etc.
Given that a Navigator can add a whole profit factor (PF) or more to the Rogue Trader vessel by charting a new Warp route, having even just two or three Navigators charting two or three routes on board a Rogue Trader vessel per year... on top of the share the House would already have in the vessel... on top of the House's extensive investment portfolios... it seems ludicrous to me that they wouldn't even have one medium-sized ship of their own.
Are there rules surrounding the PF and ship points (SP) of organizations aside from Rogue Trader dynasties? Or maybe rules to use PF in lieu of SP for such organizations? Are there any examples anyone can point to that could help determining appropriate sizes/strengths of vessels or fleets?
Thanks!
